Description

I get an exception when creating an instance of a class actor that contains a relation:

1. place composite actor on canvas
2. create a relation between 2 actors inside composite actor
3. make composite actor a class
4. create instance of class

I also get this exception when loading a model with instances of class actors.

The gui reports the exception originates at ptolemy.moml.MoMLParser.startElement(), but it is actually:

java.lang.NullPointerException

The problem was a result of restructuring the code to allow using width inference in model transformation and pTera. Sorry for the inconvenience.
